Material allows high-quality car interior
Daplen EE188HP, a thermoplastic olefin compound (TPO) has been used on all visible, injection moulded interior trims of the Mercedes C-Class interior.
Materials provide scratch-free van
The high melt flow rate of Borealis' Daplen EE103AE enables Ergom to use straightforward production techniques for the bumper of its latest Ducato van.
BMW required improved production cost, safety, high-quality aesthetics and environmental performance.
The resulting TPO fender is the most complex and highly integrated, class A body application to be seen in production to date.
It is the first time that a fender integrates such parts and functions as headlamp reinforcements and wheel housing, cleaning systems, airbag sensors, and cooling devices.
It rovides a 50% lighter-weight alternative to traditional steel components.
The fender's pedestrian protection absorber makes the new BMW X5 fulfil new EuroNCAP pedestrian safety regulations for 2010.
In line with these regulations, the fender can deform up to 80mm on impact, reducing significantly the potential for major injury to a pedestrian in the event of a low-speed collision.
Daplen was also selected for its dimensional stability, which prevents warpage caused by expansion and contraction.
It also creates an optimal design blend with the rest of the steel exterior body of the new BMW X5.
It provides the Class A surface appearance required.
Added to this, Daplen EF341AE meets Plastic Omnium's specific requirements regarding offline painting and, as a ready to use material, ease of processing.
Borealis provided mould design and process management support to the component manufacturer to facilitate production.
Klaus Maureder, Application Marketing Manager Borealis' Business Unit Automotive and Appliances comments: "The creation of the first 100% plastic one-module fender is a breakthrough for the automotive industry".
"Such a lightweight, integrated solution impacts not only on ease of production and associated costs, but allows automotive manufacturers to raise pedestrian safety performance to new levels without affecting design or functionality".
The innovation is the product of a long-term co-operation between Borealis, component manufacturer Plastic Omnium Auto Exterior and the BMW Group.
Borealis' contribution, Daplen EF341AE is a high-end 30% mineral filled TPO based on proprietary Borstar technology.
